PI2SHB new frequency

28th of November 2015, we changed the frequency of PI2SHB, the analogue 70cm voice repeater for ‘s-Hertogenbosch.
To maintain and hold the licence we were told by the Dutch Telecom Agency to change the repeater frequency.
We’ve changed the frequency from 430.2375 MHz to 430.1750 MHz.
There for we had to overcome the problem of the x-tal based oscillator.
For the moment it runs on a PLL system, but soon it wil be replaced with a dedicated x-tal based LO.
